FOLDER AT TACHMEN T Fort snwine MACHINES.

Application filed February 16;1928.

This invention relates to an attachment designed primarily for use in connection with machines used in sewing shirts and other garments utilizing facings for buttons and buttonholes. i

Heretofore it has been necessary for the operator to use one hand to properly guide the facing into the machine and control the feeding thereof while the handling of the shirt in the machine has been effected solely with the other hand.

It is an object of the present invention to provide a simple, compact and efficient attachment which can be connected either to a 1 left hand or a right hand folder and will properly guide the facing into-the folder under proper tension without requiring handling by the operator who can thus use both hands in taking care of the shirt or other garment being stitched.

Another object is to provide a device which can be adjusted easily to control the tension of the facing and which, after once being placed in position, requires practically no attention from the operator, thereby greatly" speeding up quantity production of the garments being fed to the machine.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made Within the scope of what is claimed, without departing from the spirit of the invention. 4 j

In the accompanying drawingsthe. preferred form of the invention has been shown.

In said drawings, Figure 1 is a side elevation of a portion of a folder to which the present invention is applied. 7

Figure 2 isan elevation of the attachment constituting this invention.

Figure 3 is a top perspective view thereof. Figure 4 is an enlarged section on line 44 Figure 1. v

Referringto the figures by characters of reference 1 designates an attaching block pro- 5 extends into the wall of the opening. Slidvided in one end with a slot 2 and mounted ,seria no. 254392.

ably and rotatably mounted in the opening 4 is a rod 6 one end of which is offsetor crooked asshown at 7 and merges into an elongated finger 8. On this finger is mounted a block 91adapted to slide and rotate but having a set screw 10 or the like for holding it against movement'relative to the finger 8 after it has sion' finger 11 is secured at one end to the block 9 and is parallel with finger 8.

In practice the slotted block 1 is placed sewing machine as shown particularly in Figure 4 and is held firmly thereto by the set screw 3. Rod 6 is adjusted to bring the guide fingerv 8 to position where a strip or tape of facing material M can be extended thereonce been adjusted relative thereto. A ten I 'astride the upper edge of the folder F of a around before engaging the folder. This maand the finger 8. Thus, while feeding into the machine, the strip material must make two bends thereby setting up a friction which will hold the material under tension andprevent it from moving too rapidly into the machine. 7 I

Obviously various adjustments can be made to meet the conditions under which the material is being used and the attachment can, of course, be used either with a right hand folder or a left hand folder."

That is claimed is:

1. An attachment for folders of the class described including a guide finger for strip material fed to the folder, means for connecting said finger to a folder, and a tension finger parallel with and adjustable angularly about the guide finger. 7

2. An attachment for folders-of the class described including. a guide finger forsstrip material being fed to a folder, means for adj ustably connecting said finger to a folder, a tension finger parallel with and adjustable angularly about the guide finger, and means for holding the tension finger fixed relative to the guide finger. I

3. An attachment for folders of the class describedincluding a guide finger for a strip materialto be fed to a folder, a folder engaging device, means for connecting the fin- V ger to saiddevice for slidable and rotatable tlfiljiirlllfilfiii; a tension finger mounted for an no. I

gular and slidahle adjustment relative to the guide finger, and means for holding the fin gers against relative movement.

4:. An attachment of the class described ineluding a block, means for attaching the block to a folder, a rod slidably and rotatably mounted in the block, a guide finger integral with the rod for engagement by strip material being fed to the folder, a block slidably mountedon the guide finger, a tension, finger 10 In testimony that I claim the foregoing as 15 my own, I have hereto afiixed my signature.
